FILLING HEAD OF BOTTLE-FILLING MACHINES.

Application filed August 6,' 1924, Serial No. 730,481, and in Great Britain August 18, 1923.

chines of the counterpressure type in which the bottle .is filled under pressure, the gas supply to the bottle being cut off and the return gas port opened before the liquor is supplied thereto, and more particularly to such machines having a fixed disc with ports formed therein into which the gas and liquor supply tubes and the gas release tube from the bottle projectand having a disc with ports therein oscillating in contact with the fixed disc. 4 I

In one such arrangement two tubes are employed and the liquor port is carried through the spindle on which the disc is mounted thereby necessitating a leather packing or gland around the spindle which is particularly objectionable when beer or similar liquid is being filled into the bottle.

The present invention consists in the combination of a stationary disc provided with a centrally arranged stem and with ports terminating in its outer face and located at substantially the same distance from said stem, together with a second disc mounted to rotate on said stem in contact with the stationary disc and having grooves in its contacting face, which grooves, when the movable disc is partially rotated, bring the gas and liquor ports in turn in communication with the bottleto be filled and on further partial rotation of said latter disk opening the snift port and returning the valve to its initial position.

The invention will be fully described with reference to the accompanying drawings. Fig. 1 is a front elevation. Fig.2 is a side elevation partly in section.

Fig. 3 is a plan with oscillating disc removed.

Fig. 4 is a front elevation partly in section with oscillating disc removed.

Fig. 5' is a side elevation of oscillating disc.

A fixed disc A is formed with a series of ports a, a a a, a connected respectively to the gas supply inlet conduit 6, the liquor inlet conduit 6, gas delivery and outlet pipe 72 to the bottle, liquor delivery pipe 6 gas return conduit 72 and snift conduit 6 open to the atmosphere. The disc A also has in its face an arcuate groove a which has one of its ends connected to the gas delivery inlet and outlet port a to the bottle.

The fixed disc A is carried by one of the rotary heads B on the bottling machine and .tion between said ports.

is formed with a central spindle A 'upon which is mounted an oscillating disc C formed with three arms C, C C adapted to engage stationary rollers on theomachine as the head rotates to impart oscillatory movement to the oscillating disc G relatively to the fixed disc A. The face of the disc C is .kept in close contact with the face of. the disc A by means of aspring 0 bearing against a washer 0a secured to'thespindle A by a nut a I The oscillating disc C has in its face which contacts with the fixed disc A a groove 0,

which, when the disc C is given a partial rotation. is brought opposite to the, liquor inlet port a. and the liquor outlet port a of the disc A and thus establishes communica- The disc C also has in its face which contacts with the disc A a second groove whichis arranged diametrically opposite to the groove 0 and extends'radially of the axis of rotation of the disc C. One end of the groove 0 is always opposite to and in communication with the arcuate groove a? of the disc A and its OPPO. site end is adapted, when the disc C is rotated, to be brought opposite'to the gas inlet port a or the gas return port a or the snift port a of the disc A. 'i I The lower part of the revolving head is formed in the usual manner with a screwed cap D for receiving the lip of the bottle being filled. The liquor delivery pipe 71 from the liquor outlet port a of the stationary disc A is arranged to project below the cap D and into the bottle being filled. The gas delivery and outlet pipe 6 from the port a of the disc A is also arranged to project into the bottle.

The liquor conduit 6 to the liquor inlet port a of the disc A communicates with the liquor reservoir and the gas conduit 6 to the gas inlet port a communicateswith the gas cylinder, the return gas conduit 1) to the return gas port or also communicates with the gas inlet conduit 1), while the snift pipe 6 to the snift port a? of the disk A is in communicationwith the atmosphere with cam surfaces of varying lengths according to the travel required for opening or closin each of the ports of the disk A.

When a bottle is placed in position all the ports in the disk A are closed with the exception of the snift port A The disc C is then rotated by the arm C to put the 10 gas inlet port a in communication with the port a through the two groovesa and c (Fig. 1). The arm C is then moved to close the port a and place the liquor inlet port'a in communication with the liquor delivery port a through the groove 0 and at the same time place the gas return port a 1n cominunlcatlon with the port a a through the grooves a and 0 When the bottle is full the arm C isactuated to return the disk C to the closed position ready for filling a subsequent bottle and the filled bottle is removed. a

A non-rotating disc or washer E provided with ports or apertures coinciding with those of the fixed disc A may be arranged be tween the disc A and the disc C.

WhatI claim as my invention and desire to protect by Letters Patent is In a bottle-filling machine embodying a head having a snift conduit communicating withthe atmosphere, a gas inlet conduit, a li uor inlet conduit provided with a valve, an a gas return conduit, and wherein Y the head carries a gas delivery and escape pipe and a liquor delivery pipe, a valve for controlling said conduits, said valve comprising a disk carried by said head and having a gas inlet port connected to the gas inlet conduit, a gas escape port connected to the gas return conduit, a gas outlet port connected to the gas delivery and escape pipe, a snift port connected to the snift conduit, aliquor inlet port connected to, the liquor inlet conduit, anda liquor outlet ort connected tothe liquor delivery pipe, al of said ports terminating in the outer face of cillating movements of said second-named disk to be brought opposite to said as in-r let port, said gas escape port, or sai snift port; said second-named disk also having a second groove formed in its contacting face and adapted, when said radial groove is opposite said gas escape port, to register with and establish communication between the liquor inlet port and liquor outlet port of said first-named. disk.

In testimony whereof I have hereunto set my hand.
